I took it as... The OP is wanting to have a a system that is permainantly fixed into one position not to have any control over the system other than simply on max fresh air or off. i say it can be done fairly easily.

"fairly easily" is a relative viewpoint I guess. All depends on time, ability and what is an acceptable level of hack up.

- Disable all vacuum pods and physically "jam" them into the desired position
- Plug all the vac lines to avoid leaks
- Bypass hot water to the heater core (sounds like this might already be done)
- Done

Push the defrost button and there'll be fresh air blowing from all vents on max blower.

The UT kit is simple also. Basically two three way vacuum switches,micro processor, vacuum controlled hot water valve,wiring harness and a few vacuum conection pieces to get it all hooked into the original system. I don't know what they're selling for these days but i feel like it's been worth the $550 that I paid. Yeah no fresh air control build in but it's not too bad to have Always fresh air and it's easy to add a very small ball valve to gain control of the fresh air function.
